Nothing fancy about the cable. I just had a bunch of ml600 cables so I used those. I have three Samsung displays connected to a DM 6x4 switcher. The other output is a sharp 80 inch. Two of them have DM-RMC-100's connected to them and the other has a scaler connected. All of them are 46" displays. I think two of them are the 6500 series and the other is the 8000 series. The other system has a single Samsung display connected and it is connected to a Pro2 in our showroom. That is an 8000 series 46 inch and has been connected since that model was available with no problems. The showroom system is using Crestrons ex-link module and the DM system is using our module.
